heartfelt

The compound "heartfelt" is a transparent English formation from the core Germanic vocabulary. Its first element, "heart," has long symbolized the center of one's emotions and innermost thoughts, a concept traceable to Proto-Indo-European ḱḗr, ḱrd-, which also gave rise to the Latin cor (as in "cordial") and Greek kardia (as in "cardiac"). The second element, "felt," is the past participle of "feel," originating from a Germanic root meaning to touch or perceive. The literal combination, "felt by the heart," elegantly bypasses the intellect to describe emotions perceived as profoundly genuine and deeply internal, evolving into its modern sense of sincere and earnest feeling.

Structure: heart (organ of feeling) + felt (perceived, experienced) - heart: From Old English heorte, of Germanic origin; related to Dutch hart and German Herz, from an Indo-European root shared by Latin cor, cord- and Greek kēr, kardia. Functions as a noun root denoting the seat of emotion. - felt: Past participle of the verb feel, from Old English fēlan, of Germanic origin. Functions as a participial adjective suffix indicating the state of having been perceived or experienced.
